Hi,
Unfortunately,we are not permitted to touch anaconda code because it would probably bring about some license issues.
My temporary walkaround against dhcp request in anaconda is providing IP statically during network installation, below
is my pxe config:
DEFAULT test
LABEL test
KERNEL test/ks-RedHatEL-AS3-GA-i386z
APPEND utf8 nofb root=/dev/ram ip=172.20.3.26 netmask=255.255.0.0 method=nfs:172.20.3.3:/iso/RHEL/rhel3-ga ks=nfs:172.20.3.3:/testinstall/project/1.4.1/kickstart.RedHatEL-AS3/172.20.3.26-kickstart initrd=csm/ks-RedHatEL-AS3-GA-i386.gz ksdevice=eth0
But each command line passed to anaconda will be cut by kernel to no more than 256 chars, how can I extend the maximum line size passed to anaconda?
Yours Sincerely,

Hao,
I found your question interesting so I poked around some. It looks like
Anaconda uses pump and not a dhcpclient. I cannot tell, if pump would
allow you to retrieve a UUID. isys.py makes a call to isys.c via
pumpnetdevice. You would want to look at /usr/include/pump.h for the
struct pumpNetIntf definition. Files net.c and isys.c work with the
information returned from pump. At this late hour it all looks
automagically to me. I believe you will have to customize Anaconda to
obtain your desired functionality. It looks like only part of the dhcp
information is used in Anaconda. There are a couple of items for S390
in pumpNetIntf. I don't know if that is the same as xSeries.
Have fun.
Greg
